I am getting this error

Wrapping the popover, like e.g.

  <nb-card-header>
    <nb-layout>
    Preview  &nbsp; <nb-icon class="centerIcon" [icon]="'question-mark-circle-outline'" pack="eva" nbPopover="Pick an iconic symbol for your item, e.g. XZY " nbPopoverTrigger="hover" nbPopoverPlacement="right"></nb-icon>
  </nb-layout>

screws up the whole UI, isn’t it possible to just make it work somehow? I’m using the ngx admin template, and inside https://github.com/akveo/ngx-admin/blob/master/src/app/pages/forms/form-layouts/form-layouts.component.html I can make use of popovers just like

<nb-icon class="centerIcon" [icon]="'question-mark-circle-outline'" pack="eva" nbPopover="Enter a Name for your item. E.g. 'Turbo' " nbPopoverTrigger="hover" nbPopoverPlacement="right"></nb-icon>

without the need for <nb-layout>.

Edit: Nevermind, no need for <nb-layout> . Just had to import the popover module, didn’t get a warning that it was missing. For everyone else reading: Open the module where the component is defined in, and

import { NbPopoverModule } from '@nebular/theme'; and

@NgModule({
  imports: [
    ...
    NbPopoverModule,
    ...
  ],
